Chapter 15.2, Problem 9STE
Give the definitions for the member function addValue, the copy constructor, the overloaded assignment operator, and the destructor for the following class. This class is intended to be a class for a partially filled array. The member variable numberUsed contains the number of array positions currently filled. The other constructor definition is given to help you get started.
| #include <iostream> #include <cstdlib> using namespace std; class PartFilledArray { public: PartFilledArray(int arraySize); PartFilledArray(const PartFilledArray& object); ~PartFilledArray(); void operator =(const PartFilledArray& rightSide); void addValue(double newEntry); //There would probably be more member functions //but they are irrelevant to this exercise. protected: double *a; int maxNumber; int numberUsed; }; PartFilledArray::PartFilledArray(int arraySize) : maxNumber(arraySize), numberUsed(0) { a = new double[maxNumber]; } |
(Many authorities would say that the member variables should be private rather than protected. We tend to agree. However, using protected makes for a better practice assignment, and you should have some experience with protected variables because some programmers do use them.)

Please help me C++ language
Please read the main function and define a class CStudent. (object array, static member, string)
Please do not change the main function and complete the program given.
【Description】
Please read the main function and define a class CStudent.
In the main funciton, two arrays of the ojbect of CStudent are define.
Please analyze the call of constructor and destructor in the process of creating and releasing objects.
1. CStudent has two private member variables：stirng name, int age.
2. CStudent has a static member count. It will be incremented by 1 when the object is created and decremented by 1 when the object is destroyed.
3. The constructor function should output "*** is contructing". The destructor function should output “*** is destructing”. "***" indicates the name of the current CStudent object.
【Input】

- User-defined Class:You will design and implement your own data class. The class will store data that has been read asuser input from the keyboard (see Getting Input below), and provide necessary operations. As thedata stored relates to monetary change, the class should be named Change. The class requires atleast 2 instance variables for the name of a person and the coin change amount to be given to thatperson. You may also wish to use 4 instance variables to represent amounts for each of the 4 coindenominations (see Client Class below). There should be no need for more than these instancevariables. However, if you wish to use more instance variables, you must provide legitimatejustification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount.

The Item class should also include: one set method, two get methods and default constructor to initialize Type to “None” and Price to 0.0. Part (2) Write a static method named findAvg that takes as parameter an array of type Item. The method should find and output the average price of all items in the array. The method prototype is: public static void findAvg (Item [] list) Write the main method to do the following: Declare an array of type Item of size 5; Ask the user to enter type and price for each item in the array Call the findAvg method to output the average price of all items.arrow_forward1- A complex number has the form a+bi , can be expressed as theordered pair of real numbers (a,b).

- Rectangle Class Observe the Rectangle class in rectangle.h, and you'll see it has two member variables: length_ and width_. These member variables can be modified with the "Setter functions" SetLength and SetWidth (aka mutator functions) and can be retrieved with the "getter functions" GetLength and GetWidth (aka accessor functions). You will be implementing two member functions of the Rectangle class: Area, and Perimeter. Notice that if a function belongs to a class, when we define the function outside of the class, we indicate that it is a member function of a class using the :: operator. For example, because Area() belongs to the Rectangle class, when we define the function in rectangle.cc, it is written as: int Rectangle::Area() { ... } After implementing these two member functions, you will implement a function, LargestRectangleByArea that compares two input Rectangle objects and returns which of the two is larger, based on its area. Implement the member function Area that…arrow_forwardThis is an object oriented programming question The code should be in c++ language Create a class Employee having a private data members E_ID, E_Name, E_Age and E_Salary.
